What is the current status of the Fi IB3-18? I've recently received (4) of them, and I'm considering purchasing more and I'm curious as to their availability. Are there production changes being made that somehow impact the IB3-18? Are there operational changes that your able to share publically? I just think you've got a great thing going, and I don't want my source for IB drivers to change in any way. Regardless, you've got a fantastic operation, and even prior to completing my HT IB build I'm really digging these drivers. Thank you and good luck
